[IPython-dev] IPython traitlet problem

[Matthias Vogelgesang]

Hi,

I am considering the traitlets module for a project of mine but there
is one big problem: All classes that derive from HasTraits cannot have
parameters in their __init__() method, which makes traitlets pointless
for general purpose classes, e.g.

class Foo(HasTraits):
    x = Float()

    def __init__(self, bar):
        pass

gives me

  TypeError: __new__() takes exactly 1 argument (2 given)

Is this behaviour intentional?

Thanks,
Matthias
